DMZ Reserved IPs

If you configured your DMZ to act as a DHCP server, you can reserve certain IP
addresses always to be assigned to specified devices. To do so, add the
hardware address of the device, along with the desired IP address, to the list of
DMZ Reserved IPs. Whenever the DMZ DHCP server receives a request from a
device, the hardware address is compared with the database. If the device is
found, then the reserved IP address is used. Otherwise, an IP address is assigned
automatically from the DHCP pool.
Before you can perform this procedure, you must enable DCHP Server mode or
DHCP Relay mode on the DMZ Configuration page. For more information, see
Configuring a DMZ, page
Click Networking > Optional Port > DMZ Reserved IPs, or from the Getting
Started (Advanced) page, under DMZ Port, click Configure DMZ DHCP Reserved
IPs (Optional).
The DMZ Reserved IPs window opens. Any existing DMZ reserved IP addresses
appear in the Available DHCP Assigned IPs (DMZ) table.
The reserved IPs need to be outside the pool of the DHCP addresses that the DMZ
DHCP server assigns dynamically.
Click Add.
Other options: Click Edit to edit an entry. To delete an entry, check the box, and
then click Delete. To select all entries in the table, check the box at the left side of
the heading row.
After you click Add or Edit, the DMZ Reserved IPs Configuration window opens.
Enter the IP Address and the MAC Address.
Click Apply to save your settings.
